Unable to execute a Java Code in vsm or vsi

  • 1.  Unable to execute a Java Code in vsm or vsi

    Posted 09-19-2017 12:00 PM

    Hi ,

     

    I am trying to execute a java code that add extra space on the right side, if a string is not of defined width.

    code is:

    //right padding

    HOST_PROCESS_ID = String.format("%-" + 8 + "." + 8 + "s", HOST_PROCESS_ID);

    or

    HOST_PROCESS_ID = HOST_PROCESS_ID.format("%-" + 8 + "." + 8 + "s", HOST_PROCESS_ID);

     

    this is giving me exception in vsm(data protocol) and in vsi(matchscript).

     

    Please let me know if we can handle this by some other way as well.

     

    Why this: #calisa when encounter a series of spaces before or after a string in incoming request(#lisa_vse_request) , it applies trim on the string. Hence I have to add padding exclusively to get my string of original length.

     

     

    Please help, It's urgent.

     

    Thanks,

    Dinesh Kumar

    The exception gives the reason why the code is failing. The String.format method takes two input arguments (java.lang.String, java.lang.Object)

     

    https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#format(java.lang.String,%20java.lang.Object...)

     

    Please retry after casting the second argument to java.lang.Object

    Hi Dinesh,

     

    Try this:

     

    HOST_PROCESS_ID = String.format("%-8.8s", HOST_PROCESS_ID);

     

    When you tried to concatenated '8' it used the character with an ASCII value of 8 - not a textual '8'.

    Hi Mike and Prem,

     

    I still getting exception in ca lisa, while same code is working fine in eclipse.

    code:

    Eclipse:

    String IBC_MESSAGE_FORMAT= "RNBP";

     IBC_MESSAGE_FORMAT = String.format("%-8.8s", IBC_MESSAGE_FORMAT);

     

    Please look into it. What else modification did I need to do for CA LISA.

     

    Thanks,

    Dinesh Kumar

    Hello Dinesh,

     

    If you add the following lines in a JSR 223 step of DevTest 9.5, it works fine - there are no errors.

     

    String IBC_MESSAGE_FORMAT= "RNBP";

     IBC_MESSAGE_FORMAT = String.format("%-8.8s", IBC_MESSAGE_FORMAT);

    return IBC_MESSAGE_FORMAT;

     

    Can you share the complete code of your VSM/VSI ? What is the version of DevTest you are using?

    Yes you are right,

     

    This is working fine in 9.5.1

    but I am currently working on v8.0.1 registry. facing error in this version.

     

    Thanks,

    Hi Dinesh,

     

    In that case, I know what the problem is.  That version of DevTest uses a BeanShell library that only supports JDK v1.4.  The String.format() method was introduced in JDK v1.5.

     

    Use something like this instead:

     

    IBC_MESSAGE_FORMAT = (IBC_MESSAGE_FORMAT + "        ").substring(0,8);

    Hi Mike,

     

    Thank you for the workaround. I have implemented a similar solution as below:

    1- Compare the incoming string with the original defined length.

    2- Add the difference with space character(" ") using for loop.

     

     

     

    Thanks,
